Dr Anderson accepted
an invitation from the University of Essex to speak about
transarithmetic and the perspex machine on Friday 27 February, 2006.
Over lunch he discussed the temporal properties of the perspex
machine. In the afternoon he toured the Computer Science
laboratories. He was impressed by the powered floor for robotics. It
is the largest powered floor in the world. It is circular, with an
area of one hundred square metres. It is supplied with an overhead
camera for tracking and has an observational gallery at the height
of the second floor with ground-floor access for researchers. It is
an excellent venue for demonstrating mobile robots.
